Strength and conditioning professionals require time efficient and effective means of evaluating the characteristics of muscular force expression among athletes. Two such methods, the DSI and the lower-body F-v profile, are used to guide the direction of training towards more velocity-dependent (i.e. ballistic strength) methods of training or towards more force-dependent (i.e. maximal strength) methods of training. While the use of both of these protocols have been recommended in the literature for a similar purpose, little research has been done in evaluating the relationship between the results of both protocols. Eighty-six resistance-trained individuals were recruited to perform both the DSI testing and F-v profile testing protocols to evaluate this relationship, as well as relationships between the components that compose each test. Correlations were calculated between DSI, F-v profile slope, countermovement jump (CMJ) peak force (PF), isometric mid-thigh pull (IMTP) PF, and CMJ peak velocity (PV) across a series of loading conditions from an unloaded CMJ to an additional 100% bodyweight (BW) CMJ condition. No significant correlations were found between the DSI value and the F-v profile slope. Significant correlations (p<0.05) were found between the DSI and CMJ/IMTP PF. Significant correlations (p<0.05) were found between CMJ/IMTP PF and measures of CMJ PV across the loading conditions. These results suggest that the DSI is not correlated to the F-v profile slope, however measures of performance used for the evaluations are significantly correlated.
